commit 43bba89656cce89964f260d46f2550ab9af00c9e
parent a2ff4975f372870c841a8c4eeeeb93d834663650

build: Always compile module support for tests

The --disable-module-* configure option removes code from the final binary but
we still build the unit tests with the disable module(s) so we can actually
test that code path all the time and not forget about it.
